: Adaptive read-ahead is enabled, which allows the controller to dynamically
calculate the optimum read-ahead size for the current workload.
•
Stripe
: Read-ahead is set to one stripe. The controllers treat non-RAID and RAID-1 vdisks
internally as if they have a stripe size of 512 KB, even though they are not striped.

WR Policy
Shown by the
details
parameter. The cache write policy:
•
write-back
: Write-back caching does not wait for data to be completely written to disk before
signaling the host that the write is complete. This is the preferred setting for a fault-tolerant
environment because it improves the performance of write operations and throughput. This is the
default.
•
write-through
: Write-through caching significantly impacts performance by waiting for data
to be completely written to disk before signaling the host that the write is complete. Use this
setting only when operating in an environment with low or no fault tolerance.
